Coaxial cable Rangeful SMA Male to SMA Female RG58/U 50 Ω, 7 m

Rangeful RG58/U coaxial cable with SMA male to SMA female connectors, 50 Ω impedance and 7 m length is designed for RF signal transmission in amateur radio, Wi‑Fi and measurement setups. The cable combines flexible RG58/U construction with SMA terminations to provide a reliable connection between antennas, radios, routers and test equipment for short to medium runs where low insertion loss and stable impedance are required.

Advantages

The cable offers a 50 Ω characteristic impedance suitable for most RF applications, while SMA male to SMA female connectors ensure secure, threaded connections that reduce the risk of accidental disconnection. RG58/U construction provides a balance of flexibility and shielding, enabling easier routing in confined spaces and improved resistance to external interference compared with unshielded leads. The 7 m length allows placement flexibility without the need for additional extension adapters.

Suitable for

• Connecting antennas to radios and transceivers in ham radio setups
• Linking Wi‑Fi routers or access points to external antennas
• Temporary or bench-top connections to test equipment and spectrum analyzers
• Prototyping and measurement tasks that require stable RF transmission over short to medium distances

Key specifications

• Characteristic impedance: 50 Ω
• Cable type: RG58/U coaxial
• Connector A: SMA male (threaded)
• Connector B: SMA female (threaded)
• Length: 7 m
• Typical use: RF signal transmission for antennas, routers, radios and test equipment

How to use

Ensure both mating connectors are clean and free of debris before connecting. Align the SMA male pin with the female center contact and gently thread the connectors by hand until finger-tight; avoid over-tightening to prevent damage to the connector threads or center conductors. Route the cable to avoid sharp bends and tight kinks; maintain bend radii greater than the cable diameter to preserve impedance and minimize signal degradation. For permanent installations, secure the cable with non-compressive clips or straps to prevent strain on the connectors.

Usage recommendations

For optimal RF performance, keep cable runs as short as practical and avoid running the coax adjacent to power lines or large metal objects that can cause coupling or signal loss. Periodically inspect connectors for corrosion or wear and replace the cable if you observe significant physical damage or increased signal attenuation during measurements.
